Representing structural uncertainty in a mesh representing a geological environment
22 Jun 21
A method can include receiving a node-based mesh that represents a geologic environment and a structural feature in the geologic environment; defining a node-based parameter space for structural uncertainty of nodes that represent the structural feature in the geologic environment; defining a hull with respect to nodes of a portion of the mesh where the hull encompasses at least a portion of nodes that represent the structural feature; for a system of equations, imposing boundary conditions on the nodes of the hull and on the at least a portion of the nodes that represent the structural feature; solving the system of equations for a displacement field; and generating a structural uncertainty realization of the node-based mesh based at least in part on the displacement field.

Automated method and apparatus for measuring saturate, aromatic, resin, and asphaltene fractions using microfluidics and spectroscopy
15 Jun 21
A method of determining saturate, aromatic, resin, and asphaltene (SARA) fractions of a hydrocarbon fluid sample, including: i) microfluidic mixing that forms a mixture including the hydrocarbon fluid sample and a solvent fluid that dissolves asphaltenes; ii) performing optical spectroscopy on the hydrocarbon fluid sample-solvent fluid mixture resulting from i); iii) microfluidic mixing that forms a mixture including the hydrocarbon fluid sample and a titrant fluid that precipitates asphaltenes; iv) microfluidically precipitating asphaltenes from the hydrocarbon fluid sample titrant fluid mixture resulting from iii); v) performing a microfluidic filtering operation that removes precipitated asphaltenes from the mixture resulting from iv) while outputting permeate; vi) performing optical spectroscopy on the permeate resulting from v); vii) determining an asphaltene fraction percentage of the hydrocarbon fluid sample based on the optical spectroscopy performed in ii) and vi); viii) sequentially separating saturate-, aromatic-, and resin-containing portions from the permeate from v); ix) for each separating of viii), measuring an optical property of the respective saturate-, aromatic-, and resin-containing portions over time; and x) determining fraction percentages of saturates, aromatics, and resins in the hydrocarbon fluid sample based on the measured optical properties of ix) and respective mass-to-optical correlation data.

Bayesian polarity determination
15 Jun 21
A device for assigning to the unknown onset of a signal in a noisy time series a probability of that onset having a signed excursion away from the trace mean including one or more means arranged to: define a polarity at a given time sample by reference to the sign of the amplitude difference between the extrema immediately before and after the given time sample in the time series; define a positive and a negative polarity probability density function; take the respective products of the positive and negative polarity probability density functions with an onset probability density function defining the probability that the onset of the signal occurs at a given time sample; and marginalize the respective products of the positive and negative polarity probability density functions with the onset probability density function over time to estimate final probabilities that the onset has a positive or a negative polarity.
